BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 495,690, dated April18, 1893.

Application filed June 24, 1892.

T0 00% whom it may concern:

Be it known that I, SAMUEL G. BURLEIGH, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State 5 of Michigan,have invented certain new and useful Improvements in Bed-Bottoms; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements, in that class of bed bottoms,which have a portion adapted to be elevated at the head in an inclinedposition, and its object is to provide the same with certain new anduseful features hereinafter more fully described and particularlypointed out in the claims, reference being had to the accompanyingdrawings in which Figure 1 is a perspective of the head end of a bedbottom embodying my invention as it appears, when inclined; Fig. 2 alongitudinal vertical section of the same; Fig. 3 the same as Fig. 2 asit appears when lowered to the horizontal position; and, Fig. 4: a planview of one side of the same as Fig. 3.

Like letters refer to like parts in all of the figures.

A A are two parallel sills which are connected by a series of transverseslats B B" B, arranged at suitable intervals and secured at theirrespective ends to said sills.

O C are slides arranged opposite each other and adapted to movelongitudinally on the sills A. To these slides are pivoted the ends ofshort sills D D, which are connected by a series of slats B B B, thesesills and slats forming a section of the bed bottom, which is free toswin g'in a vertical plane on said pivots, and be elevated at one end asshown, whereby the head of the bed may be raised at pleasure.

E E are braces preferably of thin metal pivoted at their respective endsto the stationary sills A A and the movable sills D D. Near the middleof said braces are downwardly projecting lugs E E in which are journaledthe respective ends of a transverse rocker bar F, to which bar arerigidly attached pawls G G engaging ratchets H H on the under side ofthe sills D D. Near the middle of said rocker bar is attached anupwardly projecting arm 1,

to which is attached one end of a contractile spring J; the other end ofsaid spring is attached to the stationary slat B by means of a cord orwire J. A cord K is also attached to said arm I, which cord extendsoppositely to said spring and under a pulley L in the upper end of theinclined part of the bed bottom, and thence upwardly to any point mostconvenient of access when the bed is completely made up. 7

By making the braces E E no thicker than the inner part of the slides O0, said braces will pass between the sills A and D when the latter sillsare lowered, and by locating the rocker bar below the plane of saidbraces, the sills A and D and the slats B B B" may be made to occupy thesame horizontal plane, when the inclined part is lowered.

The braces E serve to maintain the movable sills D in line with thestationary sills A A, and also in position longitudinally on the same.The slides O 0 move on the sills A, as said movable sills are raised andlowered. Said braces E, in conjunction with the pawls G and ratchets A,also serve to sustain the inclined part of the bed bottom in the variouspositions. The spring J tends to turn the rocker bar and engage thepawls G with the ratchets H, and by being connected to the stationaryslat B at one end as the rocker bar approaches said slat in the arc of acircle about the lower pivots of the braces E, the tendency is to reducethe expansion of the spring, due to the turning of said rocker bar. Ican thus use a shorter spring than would be required if attached to somepartof the inclined part of the structure. By pulling on the cord K theupper end of the inclined portion is lifted, and the pawls disengaged,when the structure may be lowered to the position shown in Fig. 3, orotherwise adjusted. WVhen said cord is released the spring J will atonce re-engage the pawls G with the ratchets H.

What I claim is 1. In combination with a bed bottom having a stationaryportion, and a portion pivoted thereto at one end by movable pivots andadapted to be elevated at the other end, braces pivoted at theirrespective ends to said stationary and movable portions, a rocker barjournaled on said braces, pawls and ratchets on said bar and movableportion, and a spring operating said rocker bar, substantially asdescribed.

2. In a bed bottom a stationary portion, and slides on the same,amovable portion pivoted to said slides at one end and adapted-to beelevated at the other end, braces pivoted at their respective ends tosaid stationary and movable portions depending lugs on said braces, arocker bar journaled in said lugs,

' sills, movable sills pivoted to said slides at one end, transverseslats attached to said movable sills, braces pivoted at their respectiveends to said stationary and movable sills, lugs on said braces, a rockerbar journaled in said lugs, an arm and pawl on said rocker bar, ratchetson said movable sills engaged by said pawls, a spring attached to saidarm at one end and to one of the stationary slats at the other end and acord attached to said arm opposite said spring and engaging a pulleynear the upper end of said movable part, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL G. BURLEIGH.
